Hmmm.... really? I'm using here a setup of 24 486's in networked
experiments with Utah's Mach4 and BSD-Lites Server. The nodes
don't have much to do apart from running the kernel, Lites and
a few special tasks for
1. NORMA port redirection
2. Management of Load Distribution data
3. and of course "payload" tasks, which got to get distributed
across the nodes.
That setup is really stable and the swapspace requirements are
really low (just a few MB on some nodes). Of course, 8 MB RAM
would be for normal usage a bit tight ;-)
The experiment could also have been conducted on newer Pentiums,
but then again, why waste $$$ on so many nodes, especially if you
can get 486s nearly for free?

I tried it and it was okay. Thanks for the hint.

Just tried it and it worked very well. Of course, I'm using swap
space and the ufs filesystem server on a UFS filesystem, not the
default ext2fs one. [I actually don't know if the ufs server works
with newer FFS filesystems, but I'll try this anyway (it may be
necessary to adapt the UFS code to FFS, probably by importing
FreeBSD's FFS code or something similar...).]
Running the Hurd in multiuser mode on those 8 MB boxes do require
approx. 1 to 4 MB of swap. Single-User and a minimal gnumach kernel
didn't need any swap space at all (!). Of course, YMMV.
